Twenty-one people were originally trapped in Hidden River Cave, an attraction below ground in Horse Cave, Kentucky—but after four of them were freed, two of the responding Horse Cave police officers became trapped themselves.

Hart County Ambulance, according to WBKO who first reported the trapping, said in an attempt to rescue the remaining 17 visitors, the two officers became trapped.

Reuters reports that a plan is in place to have the trapped visitors and policemen move to a safer passageway until the water levels become lower, which have quickly risen due to a recent flash flood from heavy rainfall.
